vue请求数据的三种方式

pm install vue-resource --save

import VueResource from 'vue-resource';
Vue.use(VueResource);

this.$http.get(地址).then(function(){

})

<template>
  <div id="info">
    <button @click="getData">获取数据</button>
    <ul>
      <li v-for="(item,index) in list" v-bind:key="index">
        {{item.title}}
      </li>
    </ul>
  </div>
</template>

<script>
  export default {
    name: "Info",
    data() {
      return {
        list: []
      }
    },
    methods: {
      getData: function () {
        let api = 'http://.phonegap100./appapi.php?a=getPortalList&catid=20&page=1';
        //此处推荐使用箭头函数。
        this.$http.get(api).then((res)=>{
          this.list = res.body.result;
        }, (err)=>{
          console.log(err);
        });
      }
    },
    mounted() {
      this.getData();
    }
  }
</script>

getData: function () {
  let api = 'http://.phonegap100./appapi.php?a=getPortalList&catid=20&page=1';
  const _this = this;
  this.$http.get(api).then(function (res) {
    _this.list = res.body.result;
  }, function (err) {
    console.log(err);
  });
}

pm install axios --save

fetchJsonp('/users.jsonp')
